Memory-constrained aggregate computation over data streams
— In this paper, we study the problem of efficiently computing multiple aggregation queries over a data stream. In order to share computation, prior proposals have suggested ins...

Optimal heuristic algorithms for the image of an injective function
The existence of optimal algorithms is not known for any decision problem in NP \ P. We consider the problem of testing the membership in the image of an injective function. We co...

Optimal Average Case Sorting on Arrays
Abstract. We present algorithms for sorting and routing on two-dimensional mesh-connected parallel architectures that are optimal on average. If one processor has many packets then...

Nearly Optimal Algorithms for Broadcast on d-Dimensional All-Port and Wormhole-Routed Torus
In this paper, we present nearly optimal algorithms for broadcast on a d-dimensional nn:::n torus that supports all-port communication and wormhole routing. Let Tn denote the numb...

The Optimal Online Algorithms for Minimizing Maximum Lateness
It is well known that the Earliest-Deadline-First (EDF) and the Least-Laxity-First (LLF) algorithms are optimal algorithms for the problem of preemptively scheduling jobs that arr...

Energy minimization for real-time systems with non-convex and discrete operation modes
—We present an optimal methodology for dynamic voltage scheduling problem in the presence of realistic assumption such as leakage-power and intra-task overheads. Our contribution...
